The article announces the release of llm-echo version 0.5, a debug plugin that simulates an LLM by echoing back prompts without actual model inference. The new version updates token usage calculations to include tool calls, system prompts, and reasoning tokens. An example shows how to invoke the plugin and view the resulting prompt and token usage.

Simon Willison released a new Newsletters page for his blog, listing all his free weekly Substack and monthly sponsor-only updates. He built the feature almost entirely using voice commands with Codex in the ChatGPT desktop app, interacting with his local Django development environment while cooking dinner. The process involved creating a new model, migration, view code, templates, and import functions to populate the database from external sources, all guided by his spoken instructions.
